B

Question 3

Briefly describe four main benefits of stretching before exercising.

Answer 3

Stretching can improve physical performance by increasing joint flexibility allowing the joint to move through a greater range of motion.Stretching decreases risk of injury by decreasing resistance in various soft tissues so there is less of a chance of exceeding maximum tissue extensibility during activity.Stretching can reduce some of the muscle soreness that results after exercise.Stretching can help realign soft tissues to improve and maintain good posture.
